Dr. Ananya Banik is a solid-state inorganic chemist working on understanding the structure-property correlation of energy materials. She received her M.S. and PhD in Chemical Science from Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore, in thermoelectrics. Afterwards, she joined the University of Giessen for postdoctoral research in solid-state batteries. She received Humboldt Research Fellowship to continue her work as a post-doctorate at the University of Münster. There, she worked on designing solid electrolytes, considering various critical aspects of solid electrolyte-electrode interface design, including ionic transport and electrochemical stability. Her research at TCG CREST focuses on the design of cost-effective solid electrolytes and solid-state battery design.

Further details of her research can be found here.
